Description
The present invention relates to the handrail of a kind of aisle that is used to move, escalator etc., it is the mentioned type of preamble as claimed in claim 1, and can be installed on the guide member.
Described handrail is well known (EP0530944A1, DE1756354A, DE1939241A and DE2129582A).Here, it has been recognized that, in service in escalator, mobile aisle etc., during handrail is by escalator, mobile aisle etc., because the dynamic stress that causes by the positive hogging bending that replaces of handrail, especially owing to shrink and twisted phenomena, the cross sectional dimensions of handrail can change in its life span.For avoiding these problems, be known that to install to make amount of contraction remain on the material in the little limit and insert thing.Yet described handrail requires to have enough gaps with respect to the surface of guide member and guiding base thereof, so that friction ring can become too big, thereby makes the propulsive effort that is used to handrail is moved on guide member can not become too big.In addition, also have to any gap of careful arm rest of people is not so that these gaps can cause any harm to the people that hand may be extend in these gaps who uses escalator.
The objective of the invention is to improve described handrail, make described handrail in its whole life span, can realize the safe operation that reaches standard and considered safety procedure, and must not apply too large driving force to drive handrail.In addition, if possible, should make that the amount of the material that is used to realize this purpose is very little.
Feature of the present invention is limited by claim 1, and further embodiment of the present invention is limited by dependent claims.
Accompanying drawing has schematically shown the preferred embodiments of the present invention.
According to the present invention, the clear distance C of the end of the curved edge of handrail adds that by total gap size C1+C2 at reference point place the width X of guiding base constitutes, this clear distance C is so selected, promptly considered the guiding base width X tolerance and after contraction and twisted phenomena that the run duration of handrail causes, total gap size C1+C2 is no more than 8mm.The span width A of curved edge 4 is chosen as big total gap size A1+A2 than the width Y of guide member at its side rib place, thereby, considering guide member in the tolerance of the width Y at the place, end of rib and after contraction and twisted phenomena that the run duration of handrail causes, total gap size A1+A2 is no more than 8mm.
When the size determined according to handrail of the present invention, departure point is positioned at the cross-sectional plane of guide member and guiding base thereof.Handrail causes the adaptation of guide member: in the mill, be necessary to make occuring as of all contractions of the cross-sectional plane that influences handrail and distortion controlled and can reappear (reproduce).Therefore, each handrail is adapted to each self-structuring of guide member and guiding base thereof.By the adjusting tool of production and semi-finished cross-sectional plane, thereby guarantee to have the reproducible shape of close tolerance.This is specially adapted to drawing processing, especially extrusion molding and extrusion process.
Here, also need in bench board test and/or calculation process, to consider the profile of handrail and in run duration handrail profile varying; The type of material behavior and the stress that takes place at run duration also can exert an influence, and described material behavior and stress types can be optimized by testing in advance.
Under or the situation about increasing constant at run duration, determined by cross-sectional plane that handrail surrounded outline by guide member and guiding base thereof at gap size.The tolerance upper limit of guide member has pre-determined the tolerance lower limit of the interior profile of handrail.So, guaranteed that handrail can be by clamping stagnation on guide member, but can easily move.So handrail is so designed, promptly during the operational process, promptly in the life span at handrail, the variation of gap size is limited by total gap size C1+C2.
If gap size reduces at run duration, then the interior profile of handrail is limited by the tolerance upper limit of span width C, and the tolerance upper limit of described span width C is relevant with the tolerance lower limit of guide member and guiding base thereof.In this case, total gap size C1+C2 should be above the value of 8mm.
Must design the size of the cross-sectional plane of handrail, make that handrail can not be adhered to guide member in its whole useful life, just can easily not move but must not apply too many power.
In both cases, people must guarantee that handrail is in operation, safety sufficiently when the people uses especially.
Therefore, according to the present invention, can make handrail be adapted to the particular pilot parts of specific consumers wittingly, and must not use large-scale especially handrail.Therefore, the present invention has further obtained the low good effect of manufacturing price.
According to embodiments of the invention, the side rib of guide member can be with respect to the flat inclination α or the K/UP of the slidingsurface of handrail; The curved edge of handrail is also in inwardly approximately crooked this angle on the direction of slidingsurface.This provides extra support function, so that overcome the lateral slip of handrail away from guide member.Protrusion rib when in this case, the side direction of guide member protrusion rib can be designed to be shorter than the non-angular layout a little.Gap size B1 between the aduncate end of the downside of rib and lateral edge should be less than 6mm.
In fact, in the present invention, can use interior stiffening device in the handrail, thereby guarantee certain lateral stiffness.
